We're all going to lose. It's inevitable. What I have to keep reminding myself is that losing is not only a part of life, it is a necessity.
At the beginning of Michael Jordan's career, he and the Bulls lost to Detroit in the Playoffs three straight years. If you listen to him talk, you would almost think it was the Pistons who were responsible for the subsequent 6 championships he won. Losing fueled him. The rage and ache of defeat created a mindset that enabled him to lead himself and his team to the pinnacle.
Yeah, he was great. But he was great because he lost and fought back.
